Definitions

• the present invention relates to a lithium manganese compound oxide and a non-aqueous electrolyte secondary battery using the same as a positive electrode active material.
• the non-aqueous electrolyte secondary batteries are larger in volume capacitance density or weight capacitance density and higher in output voltage than the aqueous electrolyte secondary battery. For this reason, the non-aqueous electrolyte secondary batteries are highly attractive for application not only to powers for small devices but also to powers for large devices.
• the content of sulfur is not more than 0.10 % by weight.
• the lithium manganese compound oxide was dried at a temperature of 300°C in an air for 12 hours and then placed at a temperature of 22°C and a relative humidity of 50% for 48 hours and subsequently heated by a thermo-balance at a temperature rising rate of 2°C/min up to 250°C (TGA-7) to find a reduction in weight for evaluation of the re-adsorbed moisture content.
